這是華裔著名物理學家徐一鴻教授的又一本關(guān)于物理學的專著。量子場論是物理學之大成，它融合了狹義相對論和量子力學，是物理學精義的集中體現(xiàn)，也是物理學最艱深的部分之一。許多量子場論的教程，寫的晦澀難懂。冗長復(fù)雜的數(shù)學公式，讓物理學的核心思想模糊不清，不知所在。物理學的專業(yè)人士，也常常不知所云，更遑論一般讀者。而徐一鴻教授的“Quantum Field Theory in a Nutshell”，無論是寫作的風格，或者是問題的闡述及處理，都一掃前非?！逗喢髁孔訄稣摚ǖ?版）》用略帶口語化的語言寫成，作者似乎是面對面與你談?wù)撚嘘P(guān)的物理學話題。體現(xiàn)作者深刻物理學智慧的內(nèi)容，俯拾皆是。用最簡潔的數(shù)學工具，凸顯物理學思想，結(jié)合輕松幽默的語言，不經(jīng)意之間，將你引入物理學問題的核心。閱讀《簡明量子場論（第2版）》給你帶來的喜悅，和喜悅之后的收獲，似乎只有“The Feynman Lectures on Physics”，與之在伯仲之間。如果想體念和分享，量子場論之美，量子場論之優(yōu)雅，你不可不讀《簡明量子場論（第2版）》。
